Abstract

Heat exchangers are widely known in industry as one of the standard components in thermal systems. Numerous studies on heat exchangers have focused on design modifications, fluid variations, and diverse applications to enhance thermal performance. This research investigates the enhancement of heat transfer performance through a combination of grooving and ribbing techniques applied to the inner pipe in a helical pattern. An experimental method is employed, starting with the fabrication of the heat exchanger, followed by simulation to observe flow and thermal phenomena occurring in the grooves. The study explores variations in flow configuration and mass flow rate. The addition of a single helical v-groove on the outer side of the inner pipe resulted in a notable improvement in heat transfer performance, as indicated by increased cold outlet temperature, convective heat transfer coefficient, Nusselt number, and effectiveness. Specifically, the simulation revealed that the presence of the helical v-groove induces temperature rise contours and velocity fluctuations at each groove location. Fluid particles travel longer paths than in plain tubes, increasing residence time and allowing more heat to be absorbed from the inner pipe and transferred to the outer pipe.
